"I don't need anger management, I need people to stop p#ssing me off"
It's not just you, TC. It takes more than one ingredient to make slop and you going to a therapist alone may help you, but not them. And they are as much the problem as you are... more so I'd say. I've spent my life in and out of therapy, and pretty much all of them agreed... I wasn't the one who needed to be there. Most who want to go voluntarily, aren't the ones who need to be there. Those around you need to go to their own just as much, but yeah, what's the chance of that happening?
God bless you, I'm praying for you to find someone to talk to. But I'm praying more for those who create the environment you respond to. May the Holy Spirit let them see their part as well, and bring peace to your home.
